If you're age 13-19 the Teen Witches Coven would be willing to accept you! We have several green witches and love having a variety of skills in our coven. There's details for applying on our page if you're interested!
There are plenty of covens to choose from, here is the link to look at them. Read their bio, see if you are interested in the coven or something sparks your interest. I hope you find one you like! If you have any questions feel free to send me a message :)
